... Middle Ear The middle ear contains three tiny bones—the hammer, the anvil, and the stirrup. The three bones act as a lever system to amplify the motion of the eardrum. • When the eardrum vibrates, the hammer vibrates at the same frequency. • The hammer strikes the anvil. • The anvil moves the stirru ...

Facts about Noise-Induced Hearing Loss
... “Noise-induced hearing loss is caused by damage to the microscopic hair cells, or cilia, which are found in the inner ear. Cilia are small sensory cells that convert the sounds we hear (sound energy) into electrical signals that travel to the brain. Once damaged, our hair cells cannot be repaired or ...
